Application of low interfacial tension scaling rules to binary hydrocarbon mixtures

Journal Article · · J. Colloid Interface Sci.; (United States)
For a given electrolyte concentration, aqueous petroleum sulfonate surfactants in contact with alkanes, alkylbenzenes, or alylcyclohexanes yield low interfacial tensions for only a single member of each homologous hydrocarbon series. For a particular equivalent weight surfactant and electrolyte concentration, the 3 hydrocarbons might typically be octane, octylbenzene, and butylcyclohexane. Appropriate mixtures of other hydrocarbon members of these series will produce low interfacial tensions if the average molecular weight is identical to octane and if phenyl and cyclohexyl groups are assumed to contribute zero and 4 carbons, respectively, to the attached alkyl side chains. Similar scaling rules are developed for groups in molecular species, such as decalin and n-methyl naphthalene.
